IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent No. [9] ,498, dated May 29,1877; application filed April 4, 1877.

To all whom it may concern:

Be it known that I, HENRY A. WHITNEY, of Cincinnati, Hamilton county,Ohio, have invented anew and useful Improvement in Tips for Gas-Burners,of which the following is a specification:

My invention relates chiefly to a means of controlling and preheatingthe gas on its pas sage to the ventage, for the purpose of securing aperfect, uniform, and economical combustion.

In the accompanying drawing, Figure 1 is an axial section of agas-burner provided with my improvements. Figs. 2 and 3 are axialsections of tips representing modifications of my invention.

The. tip A may be of lava, steatite, or other approved material, and hasa downward prolongation within the pillar, which may be simply anextension of the tips substance, as in Fig. 3, or may be a tubularattachment to the tip, as in Figs. 1 and 2. This prolongation is closedat its lower end, and pierced on its vertical portion by a number oforifices, b, whose aggregate area is less than that of the slit orventage a, and of which the lowest is some distance above the saidclosed bottom.

Instead, however, of entering the tip, the upper end of the check-tubemay be enlarged to embrace it, as in Fig. 2; or the tip itself may beextended downward, suitably pierced, as in Fig. 3, and closed at bottomby a plug of the same material.

The appendage or prolongation B becomes heated by reason of its closeincorporation with the tip proper, and acts to warm the gas before itreaches the ventage, so as to secure perfect combustion. It also, inconsequence of the relative smallness of its passage in the aggregate,operates to check and modulate the flow of gas, and to thus effectuallyprevent wastage and blowing.

This arrangement is practically much superior to such as have theregulating-orifice in the extreme bottom of the tube, which latter soonbecomes clogged and useless from the settling of the deposits from thegas, thereby interfering with the uniform supply of gas, and finallyrendering the burner wholly inoperative.

On the contrary, my regulating-orifices, being in the tubesperpendicular wall, and a considerable distance above the tube-bottom,remain out of danger of such interference during the ordinary life-timeof a burner. Moreover, by the use of a number of very minute orifices,the gas is separated into a number of finelydivided currents, in whichcondition it is more readily and uniformly rarefied by the heat of thetube, which secures a much more perfect combustion.

The above arrangement is also much more effective than those whosecheck-diaphragms, not being either an integral part of or in directcontact with the tip, fail to receive therefrom the amount of heatnecessary to effect the purpose, and are further objectionable becauserequiring a modification of the pillar, while my tip is complete initself and applicable to any common pillar.

I do not broadly claim a gas-tip having a tubular downward projection,partially closed at bottom, to constitute a check; nor do I claim agas-check which is not a direct pro-' longation from or of the tipproper.

I claim as new and of my invention 1. A gas regulating or controllingcheck or strainer, B, attached to or prolonged from the lower end of thetip A, closed at bottom, and having, some distance above the bottom, aseries of minute perforations, b, whose combined area is less than thatof the outlet, substantially as and for the purposes set forth.

2. The gas-tip A, Fig. 3, whose lower portion, within the pillar, isclosed at bottom, and communicates with the gas-supply through minuteorifices, b, in its vertical wall, substantially as set forth.

in testimony of which invention 1 hereunto set my hand.

HENRY A. WHITNEY.
